This is a maternity girdle by Wacoal. Originally, it's convenient for supporting the belly and lower back like a belly band from the middle to late stages of pregnancy. I only wore it a few times around 5-6 months of pregnancy because I wanted to wear lighter clothing due to the season. This one is size M, which is for people who wear M.L. *It was folded and stored, so there are a few wrinkles, but it has been home-cleaned. For reference, before pregnancy, I was 150cm tall and weighed 45kg. Just before delivery, I was 52kg, but I was around 48kg when I was wearing this. Please comment beforehand if you have any questions.
